Atheros driver doesn't work with ACPI enabled

[Jeffrey Katcher]

Hardware: IBM Thinkpad T40 with IBM Atheros A/B Mini-PCI card
Software: FreeBSD 5-current (as of yesterday)

I posted this earlier to the -current list, but I've isolated it as being an
ACPI thing.  If I boot with ACPI disabled, I can kldload if_ath, up the
interface and go.  With ACPI, I can kldload the driver, but I get unending
hardware error reset messages when I up the interface.

Thanks,

Jeff Katcher
